20 yrs. ago I was running RN12YC Champions , which don't seem to be available now. I have been offered a choice of Bosch 4218 or Autolite APP65.I have a 4.2 w/9:1 pistons.Any suggestions?

Get an new parts store. Champion changed their numbering system but a good parts store will convert the number and when you open the box the correct (old) number is on the plugs. George Camp
